Process for removal of quaternary ammonium salt |
| abstract |
The present invention relates to a process to remove quaternary ammonium salt (QS), from brine solution. The process uses an adsorbent selected from the group consisting of activated carbon and pyrolyzed sulfonated polystyrene divinylbenzene resin, or mixtures thereof which aids in removing the quaternary ammonium salt (QS). The process can be generally carried out at a temperature ranging from about -10 °C to about 90 °C, at a pH ranging from about 1 to about 13. |
